To-Do Filter Warning

[cesalo]

Is your feature request related to a problem? Please describe.
When using the "Filters" option (tested with the status field) and choose for example to list all To-Dos that are blocked:

• If I go to another view, i.e. Dashboard or Milestone and then go back to To-Dos the filter is not showing up which could mislead the user to think is seeing the complete list of To-Dos.

• Even if I clicked in the same view To-Dos the filter options go hidden.

Click in To-Dos link again or go to another option and the go back to To-Dos:

Describe the solution you'd like
If the Filters option are being used they should remain visible every time a user goes to the To-Dos section or at least some sort of warning that a Filter is in place.

Additional context
It seems this is just affecting the status box not the other fields that are more in the style of combo boxes.
